HCUPnet is a free, on-line query system based on data from the Healthcare Cost and Utilization Project (HCUP).
It provides access to health statistics and information on hospital inpatient and emergency department utilization.

HCUPnet is based on aggregate statistics tables to speed up data transfer and protect individual
records, so not all possible queries can be addressed. If a query is not possible, HCUPnet
will not allow you to choose certain parameters. If there is a query you'd like to see
that HCUPnet does not support, please write us
at hcup@ahrq.hhs.gov.
